Default .48 AR turbo side for A/T?

Hi, First of all, I have an accord with a stock K24a4 (2.4L) motor with an A/T.

I am using a log manifold with a t3/t4 turbo with an A/R of .60 comp side and .63 turbo side.

Since my car is AT, ECU decides when to shift. My turbo starts to spool about 2700rpm but tranny shifts early thats why boost is not properly utilized. I am planning on changing the hot side of my turbine to a .48 A/R instead of the .63 so it will spool up earlier. What do you guys think?

I don't want high numbers, maybe 250whp with a great throttle response. I don't want to just feel the boost when in WOT.

BTW, no plans on doing a MT swap.

Thanks a lot guys

the smaller hot side will make less power. It will spool faster your auto will still shift at redline so whats the problem.
